How to Reduce Image Size for Websites
Slow pages are often 4000px photos stuffed into a 1200px slot. Reduce size for websites by matching dimensions, then using a careful encode — not by crushing quality on a huge canvas.
Quick take: Resize → compress/convert once → upload. Prefer WebP/AVIF for photos; keep masters offline.
1. Resize to the layout
Set width/height to what the template actually shows (hero, card, thumbnail). Use the Image Resizer before any compressor.
2. Compress or convert
Open the Image Compressor or JPG/WebP tools. Moderate quality settings usually beat tiny files that look soft.
3. Ship a modern format when you can
JPG→WebP or PNG→WebP often drops weight further for the same look. See JPG vs WebP for websites when choosing.
Key points
- Pixels first, then quality.
- One careful encode beats repeated saves.
- Link compressors and converters — both help size.

FAQ
Is compressing the same as converting?
Compression shrinks bytes; conversion changes format. Many web workflows do both (for example JPG → smaller WebP).
